The Inogen 5L At Home Inlet Filter protects the concentrator and keeps dust, pet hair, and other air-borne contaminants away from your oxygen unit.
The Eco-friendly filter protects the air intake screens and helps keep dust mites, pollen, and other contaminants away from the air intake vents. Maintaining an effective particle filter will also help extend the life of the Inogen at Home concentrator unit by keeping it free of unwanted particles.
The filter should be replaced when it starts to degrade, usually 3 to 5 years, depending on use.
